Phosphor Bronze Wire

Product Description

Phosphor Bronze wire is a wire cooled predominantly by conduction to the ends. A negative slope means that as the wire heats, the cooling of the center section becomes poorer, leading to greater temperature rise. A good alternative, Phosphor Bronze wire material is a relatively low resistivity alloy with a monotonically rising thermal conductivity, such as phosphor bronze wire.

Product Application

Phosphor bronze, or tin bronze, is a bronze alloy that contains a mixture of copper, tin and phosphorous. Phosphor bronze alloys are primarily used for electrical products because they have superb spring qualities, high fatigue resistance, excellent formability, and high corrosion resistance. The addition of tin increases the corrosion resistance and strength of the alloy. The phosphor increases the wear resistance and stiffness of the alloy.

Phosphor bronze C544 is one of the finest bearing alloys the industry has to offer. Phosphor bronze is available in sheet, strip, plate, wire, rod and bar.
